Method and system for controlling the temperature of an engine

Abstract

A system for controlling the temperature of an engine, which includes at least one cylinder. The system includes a turbocharger and at least one air-nozzle. The turbocharger includes exhaust-gas-inlet-port, an exhaust-gas-outlet-port, an air-inlet-port, a compressed-air-outlet-port, a turbine and a compressor. The exhaust-gas-inlet-port is coupled with the exhaust-gas-outlet of the engine. Exhaust gas from the engine rotates the turbine, which rotates the compressor. The compressor draws air from the air inlet port, compresses the air thereby increasing the pressure thereof, and provides the compressed air to the compressed-air-outlet-port. An inlet of the air-nozzle or nozzles is coupled with the compressed-air-outlet-port. The air-nozzle or nozzles are directed toward a respective one of the at least one cylinder, and directs a flow of air toward the respective one of the at least one cylinder.

The invention claimed is: 
     
       1. A system for controlling the temperature of an engine, said engine including at least one cylinder, said system comprising:

       4. The system according to  claim 1 , wherein said at least one nozzle is one of:
 a plain orifice nozzle; 
 a shaped orifice nozzle; 
 a pressure swirl single fluid nozzle; and 
 a solid cone single fluid nozzle. 
 
     
     
       5. The system according to  claim 1 , further including at least one pressure regulator respective of at least one of said at least one air nozzle, fluidically coupled between said respective at least one of said at least one air nozzle and compressed air outlet port. 
     
     
       6. The system according to  claim 5 , further including a controller, coupled with said at least one pressure regulator,
 wherein said controller is configured to regulate air pressure provided to said at least one air nozzles via said at least one pressure regulator. 
 
     
     
       7. The system according to  claim 6 , further including at least one sensor, coupled with said controller,
 wherein said sensor is configured to measure information relating to a respective engine parameter and to provide measured information relating to a respective engine parameter to said controller, 
 wherein said controller is further configured to receive said measured information from said at least one sensor and to regulates the pressure of the air provided to each one of said at least one air nozzle by controlling a respective one of said at least one pressure regulator. 
 
     
     
       8. The system according to  claim 6 , wherein said controller is coupled with said turbocharger, and
 wherein said controller is further configured to control the operation of said turbocharger. 
 
     
     
       9. The system according to  claim 1 , wherein at least two nozzles are directed toward said outer portion of said at least one cylinder. 
     
     
       10. The system according to  claim 1 , further including a humidifier, coupled between said turbocharger and said at least one nozzle,
 wherein said humidifier is configured to introduce moisture to said compressed air. 
 
     
     
       11. The system according to  claim 1 , further including a humidifier, coupled with said turbocharger at said air inlet port,
 wherein said humidifier is configured to introduce moisture to air being input to said turbocharger. 
 
     
     
       12. The system according to  claim 1 , wherein said flow exhibit one of:
 a cone shaped pattern; 
 a hollow cone shaped pattern; and 
 a solid stream pattern.
